I am doing some work in the context of Gaborone, Botswana. We are looking at trying the pedestal grazing system as developed in Cuba. The pedestal system utilizes a frames covered in mesh with legumes growing on the frame, combined with grass corridors between the mesh frames. The cattle can graze on the growing tips of legumes growing on the mesh frames, while the legume pods can also be harvested from within the frame. (see image below) This creates more grazing area and more food production per unit area. If you are familiar with this system, do you know how many cattle per grazing area are achievable and the crop rotations required ?

Sorry I am not an expert on this.
